Ingredients

Scale

Cookies

  • 20 Oreo cookies

Dairy & Toppings

  • 14 ounces of sweetened condensed milk (1 14-ounce can)
  • 1 8 ounce container of Cool Whip, thawed for about 15 minutes before starting

Baking

  • 1 box of chocolate cake mix (standard size, about 15.25 ounces)
  • ¾ cup of butter (1 ½ sticks or 12 tablespoons), cut into 12 pats or smaller pieces

Instructions

  1. Preheat the oven: Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish with butter or non-stick cooking spray to prevent sticking.
  2. Layer the Oreos: Arrange two layers of 10 Oreo cookies each evenly across the bottom of the prepared baking dish, creating a solid base.
  3. Add the sweetened condensed milk: Pour the entire 14-ounce can of sweetened condensed milk evenly over the Oreo layers to soak and add rich sweetness.
  4. Spread Cool Whip: Using a spatula, spread the thawed 8 ounces of Cool Whip evenly over the sweetened condensed milk layer for a creamy topping.
  5. Sprinkle cake mix: Evenly sprinkle the entire box of chocolate cake mix over the Cool Whip layer. Use a fork to break up any lumps and create an even surface.
  6. Add butter: Cut the ¾ cup of butter into 1-tablespoon slices or smaller pieces and distribute them evenly over the top of the cake mix. Do not stir or mix in the butter; it will melt and create a crisp topping while baking.
  7. Bake the cake: Place the assembled dish in the oven and bake at 350°F (175°C) for 40 to 45 minutes, or until the top is golden and bubbly around the edges.
  8. Cool and serve: Remove the cake from the oven and allow it to cool slightly before serving to let the layers set and make serving easier.

Notes

  • Make sure the Cool Whip is thawed but still cold before spreading to maintain the desired texture.
  • Do not stir after adding the butter on top; it melts during baking to create the signature crispy crust.
  • Use a 9×13-inch baking dish for best results and proper cooking times.
  • Allow the cake to cool slightly before serving to prevent the layers from falling apart.
  • For an extra indulgence, serve with a scoop of vanilla ice cream or drizzle with chocolate syrup.
